Question

A new training plan is being touted as being able to improve the free-throw shooting of young athletes. You coach the sophomore team at a large high school and have 20 kids on your team. As important as the making of free throws is, you decide to try this ballyhooed new teaching technique on your team. At the beginning of the season, the students are asked to shoot 50 free throws each and the total made by each is recorded. During the season, when working on free throws, you use the techniques suggested by the new program. At the end of the first two months of practice, the kids again shoot 50 free throws and the total is recorded. Here are the results: Two Start Months 41 43 40 43 19 21 48 48 35 38 23 27 29 31 41 46 40 44 11 13 47 48 26 29 35 37 29 32 16 21 39 43 25 28 21 24 10 13 38 42 What do the data suggest about the new training technique? Begin by identifying a statement to be tested, the random variable(s) involved and any assumptions you make, level of significance, the statistical hypotheses to be tested, the test statistic and critical region. Then, either by hand or using SPSS (provide all SPSS output you use), do the hypothesis test, make a decision about the hypotheses, and draw conclusions that would help decide whether to continue using the new method.
